Jeffrey Epstein taught math and science at The Dalton School in New York

Some former pupils noted he was particularly forward with female students 

Epstein who was 20 at the time, was seen a charismatic teacher who at times acted more like a friend than an authority figure to students, especially girls

Epstein had no college degree when he was hired to teach 

Epstein, now 66, was arrested last Saturday night in New Jersey facing sex trafficking charges alleging he abused dozens of underage girls in early 2000s
